FIIEL-CHARGING AND CHARGE-FORMING APPARATUS FOR INTERNAL-COMBUSTION ENGINES.

' To all whom it may concern:

Morgan City, in the parish of Saint Mary and State of Louisiana, have invented certain new and useful Improvements in Fuelf 11 h ft d'sclosed and articularly u y erema er 1 P respectively, with the heads 11 of the vertical sectional view liable to get Charging and Charge-Forming Apparatus forlnternal-Combustion Engines; and I do hereby declare the following to be a full, clear, and exact. description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. I

The present invention relates to multlcylinder explosive engines, and partlcularly to a fuel charging and explosive charge forming apparatus therefor whereby to use fuel-of a lower and cheaper grade thanis ordinarily employed, to the end of effecting greater economy infthe running of the engine and Without any loss of efllciency.

The invention further contemplates a construction of apparatus of the type in question which may be equipped to any ordinary well built engine w1thoutrequiring any appreciable alterationln the engine structure; and one'whereln the 0on struction is not complicated, and'not ea'silyout of repair.

With these and other objectsin view the invention consists in the novel details of construction and combination of parts more pointed out in the claim. p

In the accompanying drawings forming a part of this application, and in which similar reference symbols, indicate corresponding parts in the several views: F1 ure 1 is a top plan view, partly in section, 0 the fuel charging apparatus. I

The invention'comprises a fuel charging apparatus operable through the engine to force charges of liquid fuel from the source of supply to the respective cyhnders of-tlie engine, and which is automatically regulable through the speed of the engine to feed such charges as are commensurate w1th' the re- Specification of Letters Patent.

quirement of the explosive mixture. The fuel thus delivered is formed into the proper charge by admixture with air through an apparatus mounted on the head of each cylinder, and such apparatus embodies means for varying the time of delivery of the air and determining the moment when the explosive mixture is admitted into the cylinder. i

The fuel charging apparatus consists of a supporting plate or frame 1, adapted to be mounted on and between two cylinders of the engine, as for instance between cylinders. two and threeof a four-cylinder engine. A plurality of pump cylinders 2, are mounted on theframe 1, and have their respective chambers each communicating with a pipe 3 leading to a source of fuel supply, and with asimilar pipe 4 connecting the pumpchamher with the mixing chamber of its respec- The several feeding and delivery pipes 3 and 4 are provided with ball valves 5 and 6 to govern the inlet and outlet flow of the fuel, as will be understood from the construction shownin Fig. 2.

plungers; and said arms are provided with rollers 12 having engagement" with a cam head 13 that is splined on a shaft 14, and said shaft is in turn connected to be driven from the crank shaft 8 -through a miter gear 15. Each pump plunger is fitted with a retraction spring 16 engagingwith the cylinder and the plunger head 11. The cam head 13 is adapted to be adjusted on the shaft 14 through the en ine governor 17 for effecting the variable t row of the several arms 9, and thereby automatically regulate the amounts of liquid fuel admitted into and discharged from the several pump cylinders. And it will be noted that this automatic regulation of the liquid fuel feed is directly controllable through the speed of the motor.

The charge forming apparatus comprises a plug or head 18 mounted on a head 19 of each cylinder 20, and which is bored to prorun "sTAWENT OFFICE.

-plunger or valve 27 operates wlthin the mixing chamber 21 to control the outlet opening 22 at determinable periods and through the operation of the motor. Said valve 27 works through a stuffing box 28 in the head of the plug 18, and the valve stem 29 is engaged by a spring 30, through the nuts 31 for seating said valve. The torsion of the' spring is regulable through adjusting the nuts 31, or by the cap 32 which has screw-threaded engagement with the end of the plug 18, as shown. A fulcrumed and two-armed lever (3334) has one arm (33) engaging with the valve stem 29, and its other arm (34) is provided with a roller 35 to engage with the cam 36 on the shaft 37 that is adapted to be driven from the crank shaft 8. The air controlling valve 38 has its stem'39 engaged by the arm 40 of a two-armed lever, and the other arm, 41, of said lever is engaged by the roller 35 of the lever arm 34, whereby to actuate the air controlling. valve through the lever arm 34 and simultaneously Withthe operation of the mixture releasing valve 21. p I From the foregoing it will be clearly seen that the proper charge of compressed air is admitted into the mixing chamber 21 at the instant of release of the explosive mixture into the firing chamber, and as a consequence liquid fuel is delivered for explosion in a highly vaporized conditon. And it will befurther. noted that ,the admixture of compressed air with the fuel is simultaneously timed to occur at the time set for release of the explosive charge into the cylinder, 2'. e. through the angular adjustment of the arm 34.

The engine cylinder is provided with the usual air intake port 42 controlled by the valve 43; the exhaust outlet 44 is controlled by the valve 45, and is in turn operated through suitable mechanism connectedwith the crank shaft 8. A perforated grid or grate 46 is mounted in the cylinder adjacent the fuel inlet 23, and has for its pur )ose to further vaporize or atomize the a mitted explosive charges due to its own heat as a result of the explosions in the cylinder.

It is obvious that those skilled in the art may vary the details of construction and arrangement of parts without departing from cam 36 with respect to the' lever the spiritof my invention, and therefore I do not wish to be limited to such features except as may be required by the claim.

' I claim:

The combination with a multi-cylinder explosive engine of a fuel charging andexplosive charge forming apparatus therefor comprising mixing chambers for the respec tive engine cylinders; a plurality of pumpcylinders; means for admitting fuel into said pump-cylinders and therefrom into the respective mixing chambers of the engine cvlinders; plungers operable in said pumpcylinders; means for actuating said plungers from the engine; means for admitting compressed air into said mixing chambers; controlling valves for said mixing chambers and air admissions, respectively; and common valve actuating means adapted to be operated from the engine to simultaneously open said controlling valves during the compression strokes of the respective pump plungers, substantially as described.

In testimony whereof, I afiix my signature, in presence of two witnesses.
